Dish Network offers the option to block channels three different ways. To keep younger viewers from watching mature programming, use a parental lock to block programs based on MPAA rating. To prevent viewing of programs on a specific channel, use a channel lock. A lock is also available to deter others from ordering pay-per-view or videos on demand without permission. Additionally, Dish Network offers the option of removing adult channels completely from the on-screen viewing guide. See the "Parental Locks" page on the My Dish website for more information.
